Yes it does seem to have helped for sure.
My apologies, I did mean the ‘Modify’ dialogue, although I think it did happen with the Revert too. If I clicked on the ‘Done’ button, I sometimes got the Modify box, or Revert box, pop up twice, and then put me back into Edit mode, after I’d clicked them.
I’ve tried an album with 106 images, and that crashed, although I’ve also done some with over 300 and it’s been fine. These are all 16MP NEF images. So not by any means a consistent issue.
